Iron 833 motorcycle security?

I am getting a motorcycle and wondering what kind of security precautions I should take.

I will likely get the Harley 833 Iron and its hands free security system. that will stop the ignition

but I assume it wont keep the bike from being rolled or lifted onto a pickup or flat bed. Would some chains be adequate for most situations or am I just over thinking this and the theft is not as big a problem as I am thinking..

Is the security system pretty noisy when or is it a silent just no ignition type system..

Any information would be greatly appreciated..
